Why Do We Put On Weight Even After Weight Loss?

Long term weight loss or sustaining the lost weight and preventing weight regain is the real issue behind obesity.

Understanding the underlying mechanisms that make it difficult to maintain long-term weight loss, needs to be studied to put and end to obesity.

Despite decades of research and billions of dollars spent each year on treatment, understanding of the underlying causes of obesity remains limited.

Obesity - Causes, Symptoms, Diagnosis, Complications, Treatment
Obesity is a condition where there is excess accumulation of body fat which poses a risk to the health of the individual. It can affect children and adults.

‘A lack of effective options for long-term weight reduction magnifies the enormity of this problem; individuals who successfully complete behavioral and dietary weight-loss programs eventually regain most of the lost weight.’

One in three American adults is affected by obesity, and it costs an estimated $147 billion a year to treat obesity and its consequences in the United States, according to the Centers for Disease Control and Prevention.

Growing evidence suggests obesity is a disorder of the body's intricate energy balance systems. Once an individual loses weight, the body typically reduces the amount of energy expended at rest, during exercise and daily activities while increasing hunger.

The combination of lower energy expenditure and hunger creates a "perfect metabolic storm" of conditions for weight gain.

Obesity during Pregnancy: Know the Risks
Women with a body mass index >30 are obese and are at a higher risk for gestational diabetes during pregnancy. Macrosomia and birth defects are risks seen in the babies.

"Because of the body's energy balance adjustments, most individuals who successfully lose weight struggle to maintain weight loss over time," said Michael W. Schwartz, M.D., of the University of Washington in Seattle, Wash., and the chair of the task force that authored the Society's Scientific Statement.

"To effectively treat obesity, we need to better understand the mechanisms that cause this phenomenon, and to devise interventions that specifically address them. Our therapeutic focus has traditionally been on achieving weight reduction. Most patients can do this; what they have the most trouble with is keeping the weight off."

"Healthcare providers and patients need to view this tendency as the body's expected response to weight loss, rather than as a sign of a failed treatment regimen or noncompliance with treatment," Schwartz said.

The scientific goal is to elucidate obesity pathogenesis so as to better inform treatment, public policy, advocacy, and awareness of obesity in ways that ultimately diminish its public health and economic consequences.
